Quiet Comfort, Tailored for the Attic

R-30 batts deliver a whisper-quiet calm while wrapping your home in a cocoon of cozy efficiency. I love the clean, unfaced profile—streamlined and effortless to layer for cathedral ceilings. Pair with crisp white attic decking and organized storage to create a polished, functional retreat above the living space. This is the kind of invisible luxury that elevates daily living from the inside out.

Handy interior light.
Number of Items: 1
It's a nice little light, those great job at lighting up the inside of the UTV I like the fact that it is rechargeable and I can recharge it from the UTV and it has a spot light is nice if u need to get out and look at some things. The mount is nice it can pretty much mount wherever you want to put it. Battery life seems to be pretty good, It's got wet and it still working fine.

Not satisfied
Number of Items: 1
Very disappointed, not sure if I just received the one bad one or if all are made cheaply. Did not even last a day and the orange cap that protects the usb charging port broke. Messaged seller on it being defective so we will see what comes of that. Update: seller responded and sending another one. The current one, while the orange end seemed defective the light itself is super bright. My son has a much larger one but I prefer this compact size and the brightness of it
